Planning objectives
Based on a high starting point, high standards, and high requirements, using the most advanced domestic smart card application mode, the following goals are achieved:
(1) Management terminal equipment based on GPRS wireless communication: According to the actual needs of customers, the cost of building a large metropolitan area network within the city is too high and it is not conducive to daily maintenance and management. Based on the existing mature GPRS wireless communication network The built management platform has significant advantages such as long transmission distance, large coverage area, fast transmission speed, and low cost price. In addition, each terminal device can be used independently or managed by the information center. The structure of the system platform is simple, and the system operation is safe and stable. The simple realization of the system’s multi-level data management greatly improves the operating efficiency of the system.
(2) The goal of digital office: build a backbone platform based on the Zhengzhou Public Welfare Public Bicycle Rental System. The car rental personnel shall go through the car rental procedures with their ID cards and receive a series of data generated by the car rental card and pay deposits. All the data generated by the information center management software and Each terminal equipment is analyzed and summarized separately. With the expansion of the scale of the leasing system and the increase of card functions, only the subsystems need to be added to achieve the goal of digital office;
(3) The goal of the all-in-one card: one card for each car hirer. This card integrates an identity card, a car loan card, and a deposit card. It represents the identity of the cardholder and the vehicle rented. It can be used as an all-in-one card in the city. The car borrower can use the card to handle all related businesses such as borrowing a car, paying a deposit, receiving a deposit, changing a car, and returning a car at any bicycle rental point in the city.
The system design combines real-time transmission and offline operation to realize all-in-one card operation and data sharing.

Public welfare public bicycle rental management system
Considering the particularity of the distributed lease management system, the real-time nature of the system is particularly important. The system management software divides the different functions into two mutually independent operation areas when designing, namely: the system management area and the operator management area. The operator’s identity is required to enter the operating area, and for different operators, only special operations can be performed. In this way, on the one hand, the possibility of misoperation is reduced, and on the other hand, the safety of the system is increased.
The terminal equipment of each rental location can be unified by the information center management platform to set the management personnel authority. Each rental location has a dedicated administrator responsible for the use and maintenance of the rental terminal. The management authority of the terminal equipment is specified by the information center management platform. Each terminal The machine will not be able to set the highest management authority by itself.
The office building attendance management system is mainly composed of system management software, GPRS wireless communication module, and rental terminals. The system software can all work under the Chinese Win98, win2k, xp platform, using VB, sql server 2000 and other advanced programming tools to complete. All Chinese, graphical interface, hotkey online help, easy to learn and understand, and easy to operate.
1. System management area: System administrator: responsible for setting various system parameters, making system cards, collecting and uploading data, and entering personnel information into various data sorting tasks. In the network version of the system, there are functions such as system users and workstation information maintenance. This area can only allow system administrators or super administrators (online version) who have been properly registered with the system to enter.
Operator: Its main task is to carry out the daily management of bicycle rental, the collection and analysis of rental records, the summary of rental records, etc., various operations of the car loan card (including: car loan card issuance, reissuance, card loss report, etc.), this area Only operators who are properly registered with the system are allowed to enter.
2. Real-time data transmission: Based on the GPRS wireless communication network, each terminal will send back its bicycle rental status to the management platform of the information center in real time. The management platform can also control and set up each rental terminal in real time.
3. Rental terminal: Its main function is to support car rental personnel to swipe the card to borrow the car, and to record relevant information of the car rental personnel. At the same time, information such as the name of the person who borrows the car, the number of the car loan card, and the deposit will be displayed on the terminal attendance machine. Upload the rental records to the information center management system in real time for data collection, summary and analysis.
